same net, 2 spacing constraint values problem

Hi all,

I have a 2 Cline segments of the different width, one is 100 while the other one is 200, they are of the same net (that's say, Net1) and

they are connected together.

i also have a dynamic shape of Net2 surrounding the Net1 clines.

I want to have two different spacing value for the two Net1 cline segments, width 100 -> spacing 150

and width 200-> spacing 250.

I created two spacing constraint sets, one is (default) Shape to Line = 150 while the other one (bigger_gap) is 250,

However, after drawing the constraint area and attach the Net_Spacing property, both portion of the Net1 Clines open a

gap of 250 with the dynamic shape of Net2, no matter how i adjust the constraint area, it is still the same.

 Any one has got idea how shall i go with this?

Thanks in advance. I am using 15.5.1
